  • Abstract
    This paper is concerned with the problem of obtaining nearly omnidirectional patterns in one plane of large conducting bodies having circular cross sections. To define the problem in terms of discrete sources, calculations were made for typical element patterns F(¿´) = 1, F(¿´) = 1 + cos ¿´, and F(¿´) = 1 + 1/2 cos ¿´. Array circumferences Z¿ from 20¿ to 40¿ were considered for the number of sources S from S = Z/¿ to S = 1.5Z/¿. Several prototype antennas were studied which partially overcome the practical problems of feeding large numbers of discrete sources.
